Questions & Step-by-Step Solutions
A 50 kg crate is at rest on a flat surface. What is the normal force acting on the crate?
Step 1: Identify the mass of the crate, which is given as 50 kg.
Step 2: Understand that the normal force is the force that supports the weight of the crate and acts perpendicular to the surface.
Step 3: Calculate the weight of the crate using the formula: weight = mass * gravity.
Step 4: Use the value of gravity, which is approximately 10 m/s².
Step 5: Plug in the values: weight = 50 kg * 10 m/s².
Step 6: Perform the multiplication: 50 * 10 = 500 N.
Step 7: Conclude that the normal force acting on the crate is 500 N.
Normal Force – The normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.
Weight Calculation – Weight is calculated using the formula W = mg, where m is mass and g is the acceleration due to gravity.
